TECHNICAL FIELD

The present invention relates to sofa beds, and more particularly to a sofa bed with the functionality of having its arm rests and back rest being placed in various positions.

BACKGROUND OF THE INVENTION

A sofa is an upholstered item of furniture for the comfortable seating of more than one person and typically has an armrest on both sides of the sofa along with a back rest. Sofas are usually to be found in the family room, living room, den or the lounge. They are covered in a variety of textiles or in leather.

Sofas may be convertible into a bed. This type of furniture is often referred to as a “sofa bed.” Typically, sofa beds are designed with a back rest and a seat deck. The back rest is used primarily for resting the back of the user of the sofa. The seat deck is used primarily for sitting by the user of the sofa. In a sofa bed, the back rest may be configured to be pushed back thereby forming a bed. However, sofa beds are currently limited in the number of positions available for sitting, sleeping or resting.

If, however, a sofa bed had the functionality of having different positions that may be used for various activities, such as sitting, sleeping or resting, then the user would have a greater selection of settings to add to the user's comfort and enjoyment of the sofa bed.

Hence, there is a need in the art for a sofa bed with the functionality of having different positions used for various activities, such as sitting, sleeping or resting, to add to the user's comfort and enjoyment of the sofa bed.

Referring to FIG. 1, FIG. 1 illustrates a sofa bed 100 in accordance with an embodiment of the present invention in its normal resting position (referred to herein as the “sofa position”). Sofa bed 100 may include two main sections, a seat deck 101 and a back rest 102. Seat deck 101 is used primarily for sitting by the user of sofa bed 100. Each side of seat deck 101 includes an arm rest 103A-B. Arm rests 103A-B may collectively or individually be referred to as arm rests 103 or arm rest 103, respectively. Each arm rest 103 is configured to be placed in one of three positions as discussed and illustrated below in connection with FIGS. 1, 6 and 7. FIG. 1 illustrates arm rests 103 both being in a resting position (lying flat along the level of seat deck 101).

Back rest 102 is used primarily for resting the back of the user of sofa bed 100. In one embodiment, back rest 102 may consist of two sections 104A-B, each configured to be placed in one of three positions as discussed and illustrated below in connection with FIGS. 1, 3 and 4. FIG. 1 illustrates sections 104A-B both being in an upright position.

Referring again to FIG. 1, seat deck 101 may include two front legs 105A-B and two rear legs (only 105C is shown) to provide support to seat deck 101 when a user sits on seat deck 101. A more detailed discussion of the interconnection of legs 105A-C to the underneath of seat deck 101 is provided below in connection with FIG. 2.

Referring to FIG. 2, FIG. 2 illustrates the interconnection of legs 105A-D to the underneath of seat deck 101 (FIG. 1) in accordance with an embodiment of the present invention. Legs 105A-D may collectively or individually be referred to as legs 105 or leg 105, respectively. Referring to FIG. 2, in one embodiment, each leg 105 of sofa bed 100 (FIG. 1) is interconnected to the underneath of seat deck 101 via a leg frame 201. Leg 105 is coupled to leg frame 201 via bolts 202A-D and washers 203A-D. Bolts 202A-D may collectively or individually be referred to as bolts 202 or bolt 202, respectively.

Bolts 202 may be tightened to leg frame 201 via hexagon nuts (only 204A is shown) which may be tightened using a spanner 205. Further, an Allen key 206 may be used to drive bolts 202.

As discussed above, sofa bed 100 has the functionality of being in different positions as discussed below in connection with FIGS. 3-7.

Referring to FIG. 3, FIG. 3 illustrates a view of sofa bed 100 with sections 104A-B of back rest 102 being partially laid down (referred to herein as the “lounge position”) in accordance with an embodiment of the present invention. Sections 104A-B are both placed in the second or intermediate position between being in the upright position (shown in FIG. 1) and in the laid down position (shown and discussed below in connection with FIG. 4).

Referring to FIG. 4, FIG. 4 illustrates a view of sofa bed 100 with sections 104A-B of back rest 102 being completely laid down (referred to herein as the “bed position”) in accordance with an embodiment of the present invention. Sections 104A-B are both placed in the third or laid down position thereby having sofa 100 form a bed. Sections 104A-B though may not necessarily be in the same position. An example of such an embodiment is discussed below in connection with FIG. 5.

Referring to FIG. 5, FIG. 5 illustrates a view of sofa bed 100 with one of the two sections 104A-B of back rest 102 being laid down (referred to herein as the “split back rest position”). While FIG. 5 illustrates section 104B of back rest 102 being in the upright position and section 104A of back rest 102 being in the laid down position, both sections 104A-B have the capability of being in a different position than the other section.

In addition to sections 104A-B of back rest 102 having the capability of being in one of three positions, arm rests 103A-B (FIGS. 1 and 2-5) have the capability of being in one of three positions. As discussed above, arm rests 103 were in the laid down position as illustrated in FIG. 1. FIG. 6 illustrates a view of sofa bed 100 with armrests 103 being at 20 degrees above the horizontal level of seat deck 101 in accordance with an embodiment of the present invention.
